DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
CIGAR LIGHTER
The cigar lighter is located in the front portion of the in-
strument panel. To use the lighter, push it in completely.
When the lighter is hot, it will release itself from contact
with the heating element. The lighter and the heating
element can be damaged if the lighter is not allowed to
release itself fully from the heating element. Cigar lighter
is not equipped with the lamp.
ASHTRAY
The ashtray is located in the lower portion of the instru-
ment panel. In case of cleaning the ashtray up, remove
the ashtray by pushing the upper button and clean it up.
The ashtray lamp is optional.
INSTRUMENT PANEL VENTS
The center and the side vents in the instrument panel
can be adjusted up and down and from side to side. The
side vents can also be aimed toward the side windows in
order to defog them.
GLOVE BOX
The glove box can be opened by pulling up on the latch
handle. The glove box must be removed in order to gain
access to the passenger-side airbag module.
DIGITAL CLOCK
The digital clock is located in the instrument panel, be-
low the defroster grille. The clock is capable of a 12 –
hour display.
INSTRUMENT CLUSTER
The instrument cluster is located above the steering col-
umn and in the instrument cluster trim panel. The instru-
ment cluster contains the instruments that provide the
driver with vehicle performance information. The instru-
ment cluster contains a speedometer, an odometer, a
trip odometer, a temperature gauge, a fuel gauge, and
several indicator lamps. For replacement of the indicator
lamp bulbs contained in the instrument cluster, refer to
“Instrument Cluster Indicator Lamps Specifications” in
this section.
SPEEDOMETER/ODOMETER/TRIP
ODOMETER
The speedometer measures the speed of the vehicle. It
consists of an instrument cluster gauge connected to
the vehicle speed sensor on the transaxle output shaft.
The odometer measures the total distance the vehicle
has traveled since it was manufactured. It consists of an
instrument cluster gauge connected to the vehicle
speed sensor on the transaxle output shaft.
The trip odometer measures the distance the vehicle
has traveled since the odometer was last reset. It con-
sists of an instrument cluster gauge connected to the
vehicle speed sensor on the transaxle output shaft. The
trip odometer can be reset to zero at any time so that the
driver can record the distance traveled from any starting
point.
FUEL GAUGE
The fuel gauge consists of an instrument cluster gauge
connected to a sending unit in the fuel tank.
The fuel gauge indicates the quantity of fuel in the tank
without the ignition switch position.
TEMPERATURE GAUGE
The temperature gauge consists of an instrument clus-
ter gauge connected to a temperature sensor that is in
contact with the circulating engine coolant.
The temperature gauge indicates the temperature of the
coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the
gauge. The engine is overheating if the pointer moves
into the red zone at the upper limit of the gauge.
INSTRUMENT CLUSTER INDICATOR
LAMPS
The instrument cluster contains indicator lamps that in-
dicate the functioning of certain systems or the exis-
tence of potential problems with the operation of the
vehicle. The indicator lamps are replaceable. For re-
placement of the indicator lamps contained in the instru-
ment cluster, refer to “Instrument Cluster Indicator
Lamps Specifications” in this section.
